Here are the energy profile diagrams, p.s. sorry couldn’t find any plain paper!
Answer:
The empirical formula of glucose is CH2O
Explanation:
The formula for glucose is C6H12O6
To calculate the empirical formula of glucose, we need to know the number of mole of each element present in the compound.
Since the moles have been given in the formula of glucose C6H12O6
There are 6 moles of carbon, 12 moles of hydrogen and 6 moles of oxygen
Since we've known the number of moles already,so we pick the mole with the smallest number and divide through with it
C - 6/6 = 1
H - 12/6 = 2
O - 6/6 = 1
Therefore, the empirical formula of glucose C6H12O6 is CH2O
Answer:
the salt is left in the beaker/ boiling bowl and the process is called cyrstalisation
Explanation:
The changes in matter/energy can be classified as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
<h3>What are physical, chemical and nuclear changes?</h3>
Matter and energy undergo physical, chemical and nuclear changes.
Physical changes are changes in which no new product is formed.
Chemical changes are changes in which no new product is formed.
Nuclear changes are changes in which no new product is formed.
Examples of each of the given changes is as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
Therefore, matter/energy undergo changes.
